A hard magnet may include a seed layer including a first component
including at least one of a Pt-group metal, Fe, Mn, Ir, and Co, a cap
layer comprising the first component, and a multilayer stack between the
seed layer and the cap layer. In some embodiments, the multilayer stack
may include a first layer of including the first component and a second
component including at least one of a Pt-group metal, Fe, Mn, Ir, and Co,
where the second component is different than the first component. The
multilayer stack may further include a second layer formed over the first
layer and including the second component, and a third layer formed over
the second layer and including the first component and the second
component.
